[Suggestion] Allow filepicker to select .csv.gz extension, as it is supported by DuckDB

[MbayeNews]

DuckDB, like Pandas, allows loading of gz compressed CSVs : SELECT * FROM 'myfile.csv.gz' works very well in DuckDB.

This is extremely practical for bigger CSVs, as decompressing them on-disk is not necessary (the decompressed version is often 5x to 10x bigger).

Could the file picker allow the selection of such compressed CSVs ?

For some reason it wasn't working as now it does!
